I have followed along with the tutorial to use ag instead of find for completions. However, I am getting an error when directly copy-pasting the _fzf_compgen_path() function from the docs.

ERR: Error fstat()ing stdin

Now, I know this error is from ag but I'm not quite sure why it is getting there. If I were to run the command directly: ag -g "" ./src (for example) I get a list of files. I've tried going through the completion.zsh file to understand what's going on but I'm lost. Isn't this (_fzf_compgen_path) the command that is called directly with the user input? Does anybody know why I would be seeing this error.

_fzf_compgen_path() {
  ag -g "" "$1"
}

So you mean this doesn't work? It works for me.

[adam-beck]

Yea that exact line doesn't seem to work. I'm wondering if I have a plugin or something that is interfering. Not sure how to debug that, though.

[adam-beck]

Since I'm inexperienced, here are the last few lines of my ~/.zshrc:

export FZF_DEFAULT_COMMAND='ag -g ""'
export FZF_CTRL_T_COMMAND="$FZF_DEFAULT_COMMAND"
_fzf_compgen_path() {
  ag -g "" "$1"
}

[ -f ~/.fzf.zsh ] && source ~/.fzf.zsh

Am I missing something else?

[adam-beck]

Interestingly, I'm also getting this using the Ctrl-t.

[junegunn]

Hmm, is it still reproducible even when you trim down your .zshrc to contain only those lines?

[adam-beck]

Commented out everything but those lines and I'm getting the exact same error. Current versions:

• Ubuntu 14.04
• zsh 5.0.2 (x86_64-pc-linux-gnu)
• tmux 2.2

[junegunn]

Strange. I can't reproduce. I have zsh 5.2 on OS X.
ag --version? If you're running an old version, please upgrade ag and see if the problem persists.

[adam-beck]

I apologize. I just installed ag yesterday via apt. I didn't realize I was so many versions behind. I was on 0.19 but after installing from source I'm at 0.31.0 and things seem to be working now. Thank you for your time and for such an awesome tool!
